Kim Kardashian on Gluten-Free Diet?

Kim Kardashian shows off her curves in an orange bikini. Kim Kardashian looked hot, hot, hot on the beach during a recent vacay in Mexico, snapped wearing a bright orange bikini that showed off her curves.

Kim hit the waves on a boogie board, soaking up the sun and surf during her getaway with sister Kourtney Kardashian and nephew Mason.

Kim is looking in top-form these days and it may all be due to a gluten-free diet.

On Friday, Kim shared an older photo of herself wearing lingerie with the caption "Gluten free is the way to be....OH Hiiiiiiiiiiii"

If you recall, Miley Cyrus has credited a gluten-free lifestyle for her recent weight loss too, as she tweeted on April 9: "Everyone should try no gluten for a week! The change in your skin, physical and mental health is amazing. You won't go back!"

Meanwhile, rumors are swirling that Kim and boyfriend Kanye West are talking about getting married, according to an Us Weekly source.

A family source tells E! Online that the rumors are "a laugh riot bunch of BS."
